摘要： An interpolated image generating apparatus calculates a motion vector reliability level indicating reliability of a motion vector used for inserting an interpolated image, the value of the motion vector reliability level being determined in such a manner that the stronger the correlation is between a source image area and a destination image area that are brought into correspondence with each other by the motion vector, the larger is the value. The apparatus also calculates a failure-preventing vector reliability level indicating reliability of a predetermined failure-preventing vector used for preventing image failures. The apparatus obtains a motion compensated image based on the motion vector, obtains a failure-preventing image based on the failure-preventing vector, and blends the motion compensated image and the failure-preventing image according to a weighted average thereof calculated by using a weighting factor based on the motion vector reliability level and the failure-preventing vector reliability level.
